    • Popping the hood on the 2014 F80 M3 reveals a cramped engine bay sporting a 450+ horsepower turbocharged inline-6 cylinder

      Here is a peak into the engine bay of the upcoming 2014 F80 M3. And yes, that engine bay definitely looks to be tight so working on it is not going to be a ton of fun. With the cramped bay and turbo (or multiple turbos) heat management will be an issue. That is why you see an aluminum water to air intercooler sitting on top of the motor. As far as power, with the new M5 sporting around 520-530 wheel horsepower stock, the new M3 should be within 100 wheel of that based on precedent.

      The E39 M5 put out about 340 wheel horsepower stock. The E46 M3 did about 275 so the E46 M3 had about 80% the horsepower of the E39 M5. The E92 M3 puts out about 350 wheel stock compared to the roughly 420 wheel horsepower of the E60 M5 which means it had 83% of the E60 M5's horsepower. If this is to follow with the new model, which it likely will to maintain the hierarchy, we can expect the new M3 to put out in the ~430 wheel horsepower range on a dynojet.

      Time will tell and as soon as more specs are revealed BimmerBoost will bring them to you.

        Yeah I got it now. They're sequential ordinary turbod. I read last year about this electric "turbo" I guess it didn't make it into production.

        Another thing you guys might find interesting is the tape on the engine cover is pretty long covering something possibly lettering. Is BMW going back to the M Power wording and dropping the M Badge or is this another motor we are looking at?
        Another thing is that everything seems to be very high in the engine bay. Is this to make space below what would traditionally be intake manifold space for a electric dynamo of some sort coupled to the flywheel?

        In the world of BMW engines that is my favorite, with the S65 just behind it. It's def not the 'best' engine, but it is has both character and great performance. If you haven't heard a 450+ hp n/a S54 - you need to - $#@!ing amazing.
        I would strongly agree with this.

        According to some insideinformation the new M3 will have a 480 hp twin turbo, DCT and the same off differential as the F10 M5, it will also be 120 kg lighter,
        Sounds promising !

        If they can make it lighter...

        Hmmm... here's a MPower Triturbo diesel picture with similar intercooling.

        Do you have any more pics of this?

        Looks like the same intercooler setup, interesting. Good post!

        That is ridiculously tight in that bay!!!!!! Puts me off the idea of tinkering with it!

        Positioning of that cooler suggests BMW think they can eliminate lag by reducing and reducing the amount of air between the turbos and inlet. Could they get any closer if they even tried?

        I don't see that as being a bad thing? It would sharpen the throttle response the n54 lacks in comparison to the s65. Less lag than the n54 for the s55 would be great
